: "Our asylum related activities include: Supporting LGBT asylum seekers: providing support & information via our helpline and in person; referring to solicitors; organising a monthly support meeting; visiting detention centres and running other social support projects."
You need to search for organizations that provide concealing and advocacy for people in your situation. Usually if you can find ONE, they know about others and can point you in the right direction.
Here is a list of nonprofit organizations in the US
. Whether or not any one of them could help, I have no idea. But, again, they are more likely to know what services are available and from whom than random people on the internet.
Obviously short of a miracle, immigrating legally to a more tolerant country is a lengthy and costly process. As others have indicated, your chances are increased if you have money to go to school in a foreign county or educate yourself in a profession that is wanted in your destination country. The main thing is to stay safe, keep positive and optimistic, and keep working on the problem when ever you can.
ETA: Her's one called the Immigration Advocates Network
. The problem is that people who work in nonprofits often have more case loads than they can handle. They may be flooded with people needing help as badly or more so than you… Just saying, be prepared. You're NOT the only person seeking help. Far from it.
